Earlier today it was announced that the Diamondbacks and free agent righty Jon Garland agreed to a one year deal guaranteeing him $8.5M, with a mutual option for a second year thrown in for good measure. Let’s take a quick look at how Garland compares to another recently signed free agent pitcher.

Holy schnikees. Pettitte’s got him beat in every category except WHIP and walk rate over the last three years, and even those are tiny differences. Of course, there is the little matter of Garland being seven years younger than Pettitte, but age isn’t much of an issue when talking about a pair of one year deals. Sure, the chance of Pettitte regressing is better than the lack of Garland regressing, but a full win regression? Not bloody likely.

So somehow, someway Jon Garland managed to get more guaranteed money than Andy Pettitte. I thought the Yankees were the ones that always overpaid?

(Oh, and as BtB points out, the D-Backs could have had Randy Johnson, who was worth nearly two more wins than Garland in ’08, for roughly the same amount of money. Ouch).

Here’s your Open Thread for the evening. The Rangers are in Pittsburgh while the Knicks and Nets are each in action at home. Also, I’m helping Dave out over at Blueseat Blogs, so make sure you check it out. You know what to do, just be nice.

Since the off-season began, I’ve heard Yanks fans mention Jon Garland as a possible solution in the rotation. Those comments have heated up a bit over the past few weeks as it has become increasingly unlikely that the team signs Andy Pettitte to fill the fifth starter void. The argument usually goes something like: “He’s a guy who can eat innings and give you league average pitching.” If we were sure this is what Garland would bring, I could see signing him. Unfortunately, the way his stats have trended make it look unlikely.

Garland made a name for himself in 2005, posting a 3.50 ERA in 221 innings, en route to a World Series title with the White Sox. However, since that season he’s not been nearly as good. Not even close. In fact, even that season his FIP was 4.24, which is not bad, but shows that his results might have been part of the randomness that baseball players experience from year to year. For more on randomness, read books by this guy. His 75.4 LOB% might have something to do with that low ERA as well.

In 2008 he walked nearly one more batter per nine innings than he did two years prior. If that was a one-year jump, it wouldn’t scare me as much. Yet his 2007 figure, 2.46, sets off a red flag. Combine this with his incrementally declining K rate, and you have one messy situation.

Moving down to his other peripherals, it paints a strange picture. His line drive rate has been pretty consistent throughout his career, right in the 22 percent range, but he saw an enormous spike in groundballs last year — 49.9 percent, which was over 10 percent higher than his 2007 campaign. This means he was giving up fewer fly balls, generally a good thing, but not when your HR/FB ratio jumps up by nearly five percent (7.1 percent in 07, 11.9 percent in 08).

No, Jon Garland probably wouldn’t be a poor choice to fill the fifth starter role. A 4.50 ERA/FIP, which is what the three projection systems (Bill James, CHONE, Marcel) have him at in 2009, is fine from the five hole, especially if it’s over 200 innings. However, the price will not match the output, and that gap becomes wider if Garland continues his downward trend. Unless he’s available for one year and around $5 million, the Yanks would do best to pass on him.
